Sierra
Monitor provides a full range of Industrial Flame Detectors designed to
meet the needs of fire and safety professionals. The Sierra
Monitor optical flame detectors, are top-of-the-line models featuring
dual and tri-spectrum designs to provide a full range of capability. Each
of the Sierra Monitor flame detectors provides 120 degree cone of vision.
Sierra Monitor is also a distributor of Spectrex Optical Flame Detectors, offering our users a wide range of UV, UV/IR and Triple IR Flame detectors in addition to the UV/IR/Visible and Semiconductor Web Bench Flame Detectors that we have been providing for many years. The Spectrex Flame Detectors have a 90 degree cone of vision.
Sierra Monitor Flame Detector
Industrial Flame Detector (3100 Series)
A tri-spectra design incorporating Ultraviolet, Infrared and Visible spectrum provides continuous and reliable flame detection. 120 degree cone of vision is provided, the largest in the industry.
Semiconductor Wet Bench Flame Detector (3200 Series)
Designed for the harsh conditions that can be found in a semiconductor manufacturing wet bench application.
UV/IR Flame Detector (3300 Series)
Designed for indoor applications, in a non-hazardous area such as a warehouse, exhibition hall or office spaces. The Model 3300 is ideal for use in areas where short line of sight is a factor.
Spectrex Flame Detector
Spectrex UV/IR Flame Detector (3500 Series)
Proven, reliable technology for detection of hydrocarbon-based fuel fires as well as some metal and inorganic fires. Incorporates a special logic circuit to help prevent false alarms due to solar radiation. High speed models are available. 90 degree cone of vision is standard.

Spectrex UV Flame Detector (3510 Series)
Self-contained optical flame detector for detection of Hydrogen, Hydrides, Ammonia, Silane and other inorganic fuels High speed models are available. 90 degree cone of vision is standard.
Spectrex Triple IR (IR3) Flame Detector (3520 Series)
The detector has applications in a wide range of industrial and commercial facilities, where the threat of accidental fire involves hydrocarbon fuels. High speed models are available. 90 degree cone of vision is standard.
Spectrex Single IR Flame Detector (3525 Series)
The detector is designed to provide early warning of flaming fires involving organic materials. High speed models are available. 90 degree cone of vision is standard.
Spectrex Hydrogen Flame Detector (3530 Series)
The optical sensors and filters have been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emitted by the hydrogen fire and the lowest degree of matching to non-fire stimuli.High speed models are available. 90 degree cone of vision is standard.
